Proportional divider for artists

General Information:

This is my version of a proportional divider / scale tool for artists. This tool is essential for accurately replicating the correct proportions from real life to paper/canvas. 

It has a modern and simple design. The 16 holes make it possible to determine the center of rotation/pivot point very precisely. To save some material and round things off, there is a honeycomb pattern at the other end.

Thanks to the small size of 19 cm in length, it is also possible to print on the Prusa Mini. 
I will also add a bigger version in the future. 

How it works:

Informative video on the subject of proportional divider from 
Mark Carder (DrawMixPaint on Youtube).

Print Information:
 

Print: 0.2 mm
Nozzle: 0.4 mm
Perimeters: 2 for the proportional divider
Perimeters: 4 for the nut and screw

Pro Tip: You can change the perimeters per model and print everything together even with different settings. Prusa wiki: https://help.prusa3d.com/article/per-model-settings_1674

Infill: Gyroid 20%
Support: Not required
Brim: Not required

Be careful while tightening the screw. Even with the 4 perimeters the screw is very fragile and can easily break. Feel free to replace the printed screw/nut with a metal one. The diameter of the holes are 6 mm.

Alternative screw has now been added as suggested by @MakerPadawan_3268882 here:

Have fun printing :)
